CLEANING BURNER INJECTOR HOLDER AND PILOT AIR INLET HOLE
We recommend that you clean the unit every three months or after 2500 hours of operation. We also recommend that you keep
the burner tube and pilot assembly clean and free of dust and dirt. To clean these parts we recommend using compressed air
no greater than 30 PSI. You can use a vacuum cleaner in the blow position. If using compressed air in a can, please follow the
directions on the can. If you don't follow directions on the can, you could damage the pilot assembly.
1. Shut off the unit, including the pilot. Allow the unit to cool for
at least thirty minutes.
2. Inspect burner, pilot, and primary air inlet holes on injector
holder for dust and dirt (see Fig. 24).
3. Blow air through the ports/slots and holes in the burner.
4. Check the injector holder located at the end of the burner tube
again. Remove any large particles of dust, dirt, lint, or pet hair
with a soft cloth or vacuum cleaner nozzle.
5. Blow air into the primary air holes on the injector holder.
6. In case any large clumps of dust have now been pushed into
the burner. Repeat steps 3 and 4. Clean the pilot assembly also.
WARNING
: Failure to keep primary air openings of burners clean may result in sooting and property damage.
CAUTION
: You must keep control areas, burner, and circulating air passageways of heater clean. Inspect these areas of
heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent
cleaning due to excessive lint from carpeting, bedding material, pet hair, etc.
The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these
holes clear of dust, dirt, and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will create soot. We
recommend that you clean the unit every 2500 hours of operation or every three months.
MAIN BURNER
Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame
present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become
blocked by debris or rust, with no flame present. If so, turn off the heater and let it cool, and remove blockage. Blocked burner
flame holes will create soot.

CLEANING ODS/PILOT
Use a vacuum cleaner, or pressurized air.
A yellow tip on the pilot flame indicates dust and dirt in the pilot assembly. There is a small pilot air inlet hole about two inches from
where the pilot flame comes out of the pilot assembly (see Fig. 25). With the unit off, lightly blow air through the air inlet hole.
You may blow through a drinking straw if compressed air is not available.
